User equipments, base stations and methods for a configurable downlink control information format

Plain English Translation

This invention relates to wireless communication systems, specifically to user equipment (UE) configured to monitor downlink control information (DCI) formats in different search spaces. The problem addressed is the need for efficient and flexible DCI monitoring to support multiple communication modes, such as enhanced mobile broadband (eMBB) and ultra-reliable low-latency communication (URLLC), which may require different DCI formats and search space configurations. The UE includes receiving circuitry configured to monitor a first DCI format and a second DCI format in different search spaces. The first DCI format may be associated with a first communication mode, such as eMBB, while the second DCI format may be associated with a second communication mode, such as URLLC. The search spaces are regions within the control resource set (CORESET) where the UE searches for DCI. By monitoring different DCI formats in separate search spaces, the UE can efficiently handle multiple communication modes without conflicts or unnecessary processing overhead. The receiving circuitry may also be configured to decode the DCI formats to extract scheduling information for downlink or uplink transmissions. This approach improves resource utilization and reduces latency, particularly for latency-sensitive services like URLLC. The invention enhances flexibility in wireless communication systems by allowing dynamic adaptation to different service requirements.
